To (1,7] 7172/0711/ HI/(rq/ (fon/cern:

Be it known that we, JOI-Ix F. MCKAY and Davm J. McK.\v,citiZens oftheUnited States, and residents ot' Bowie, in the parish et' Lafourche andState ot' Louisiana, have invented a new and Improved Overhead-ConveyerSystem, ot' which the vfollowing` is a tull, clear, and exactdescription.

Our invention relates to certain improvements in overhead cableways orconveyors, especially those intended for conveying' or skidding' logs.These apparatus are g'enerally provided with a main or track cable onwhich a carriage runs, this carriage being' provided with anouthaul-line and with a skidding'line, one end of which is attached tothe hoisting-engine and the other end aft'ter running' through a blockon the carriage is provided with means for eng'ag'ingthelog's. Dit'-iiculty has been experienced in drawing' out this skidding'line at theend otl the outhauling' movement of the carriage, and our presentinvention contemplates a novel means for drawing' or paying' out theskiddingline after this outward movement of the carriag'e andpreparatory to loading' or reloading' the same.

Our invention also contemplates an improved loading'carriag'e which isemployed in connection with one ot' the g'uides for the main cable andwhich serves to permit loading' the logs on a wagon, railway-car, orother vehicle.

The invention also contemplates an improved tension-bloek which isemployed in connection with devices for maintaining' the niain or trackcable at the proper tension, and,

finally, we have provided an iniiproved double-block structure, attachedto the carriag'e and accommodating' the skidding'line outhaul and also apeculiardetachable section for the skidding'- line, which detachablesection g'reatly Vfacilitates the loading' ot the conveyer, all of whichwill be made fully to appeal' hereinafter.

Reference is had to the accompanying' drawdouble block which is appliedto the carriage` to acconnnodate the skidding'dine and the skidding'lineouthaul. said block on the line 3 3 of Fig'. 2.

Fig'. 3 is a section ot' Fig'. is

a .section on the line 4C 4 of Fig'. 2. Fig'. :3 is a side elevation ot'one et' the blocks employed in connection with the tension-line for themain cable. Fig'. 6 is a section thereof on the line G t ot' Fig'. Fig'.7 is an end view of this block shown in Figs. andt. Fig'. S is a sideelevation ot' the novel loadiiig-carriage. Fig'. 9 isa plan view ot thesame, and Fig. 10 is an end elevation looking' in the direction of thearrow 10 in Fig'. S.

12 indicates a main cable which is attached to and supported by what arecommonly known as the "head-tree1-1aud y"tail-tree 15. (.lableways ot'the type to which our invention relates are usually erected in thet'orest, and trees are employed for the cablesupport, although it isobvious that especially-erectral poles or any other such means could beemployed. 'lhe main cable 1Q is attached in any suitable manner to thetailtree .'15, and it is connected to the head-tree 11 through themedium et' a tension-line 1G and tension-line blocks 17. Thistension-line is rove over the blocks 17 down to a tensiondrum 18 inessentially the manner set t'orth in our prior patent fortension-reg'ulators for overhead cables, No. 757,052, dated April 19,190%l 19 indicates a g'uy or g'uys for the tail-tree, and Q0 indicates ag'uy ior the head-tree.

The blocks 17 are of the peculiar construction illustrated in Figs. 5,6, and 7. This structure comprises a shell formed of an integralcasting` and comprising' cheeks 17", connected at their outer ends by aweb 1'7" and joined at their inner ends by a head 17", having' anorilice .17l therein. 1'7c indicates a sheave which is carried on a pin1`7f, the pin passing' throug'h the shell, as usual, and having' anoil-groove 17"r therein. This groove communicates with oil-pockets 17",Vformed in the shell o1" the block and having' oil-feeding' orilicesleading to the outer surfaces thereof, as shown. lhe block is attachedto its support or to the main cable, as the case may be, by passing' thestrap or pennant or the big'ht of the main cable into thecavity 17l andaround a pin 17. This pin is connected to the shell ot' the block by achain 17 and is held in place by a linchpin 17, also connected to theshell by a chain 17".

21 indicates the skidding'carriag'e, which may be ot' any desired formand which acts on the main cable 12 in the usual manner.

indicates an outhaul-line which is attached to the carriage and roveover a block IOO lIO

23, attached to the tail-tree l5, thenee backrl to guide-sheaves 24,attached to the carriage 21, and over a block Q5, attached to theheadtree 14, and thence down to a drum 26 of the hoisting-engine. Byhauling in on this line 22 its lower run will be drawn outward, and withit the skidding-carriage 21 will move toward the tail-tree.

27 indicates the skidding-line, which passes from a drum 28 of thehoisting-engine upward over a block 2S) on the head-tree 14. At thepoint 30 the skidding-line is provided with an eye, and this eye isadapted to be engaged by sister hooks joined by a chain or otherwise tothe end section 27 of the skidding-line. This end section passes througha double block 31, around the lower sheave thereof, and thence descendsto the ground, it being provided at its lower end with a means 32 forengaging it with a log or logs. ln the ordinary operation of theseapparatus when the skidding-line is engaged with the log it is hauledin, bringing with it not only the log, but the carriage 2l and itsattachments. As the carriage is hauled out by the line 22 thelog-engaging means jam in the block 31, and the skidding-line is hauledout with the carriage. At the end of this outhauling movementit isnecessary to further haul the skidding-line, so as to drop the means 32to the ground. For this purpose we provide a skidding-line outhaul 33,which is wound around the drum 34 of thehoisting-engine and passes uptherefrom over a block 35, attached tothe head-tree. From this point theskidding-line outhaul 33 passes around the upper sheave of the doubleblock 31, and thence back toward the head-tree and is spliced into orotherwise joined to the skidding-line 27 at the joint 36. New thereforeafter the operation of outhauling the shielding-carriage 21 and line 27the drum 34 should be operated, causing the outhaul 33 to eXert on theskidding-line a further outhauling strain, drawing said line through theblock 31 and dropping the tongs 32 or other log-attaching means to thegrou nd, so that the tongs may be conveniently engaged with the logs.

rlhe peculiar double block 31 is illustrated in Figs. 2, 3, and 4. Saidblock comprises a cast-metal shell having cheek-pieces 81a, connected bywebs 31h, as shown. These parts may be integral or otherwise andprovided with stay-bolts 31C, as illustrated. 31 indicates a becket,which is swiveled onto the upper end of the block, as shown. The uppersheave 31C is mounted on a pin Blf and fits snugly between thecheek-pieces` and the lower sheave 31g is mounted on a pin 31h. Betweenthese two sheaves the cheek-pieces are spread apart to form an enlargedspace 311, which permits the sister hooks and chain on the upper end ofthe skidding-line end section 27 to bernoved freely through the shell ofthe block. In the operation of the apparatus a plurality of these endsections 27 are provided, and while one is being' employed to track orskid the logs toward the head-tree the workmen toward the tail-tree maybe engaged in fastening another of said end sections 27 to another groupof logs, so that when the skidding-carriage is returned for another loadthey have only to disengage the end section 27 first employed andreengage the sister hooks and chain of the second end section with theskidding-line, thus saving much time in loading' the conveyer. Thepeculiar forrn of the double block, particularly the enlarged opening3l1 above the sheave 31g, greatly facilitates this operation.

The loading-carriage is mounted on the guy 2O of the head-tree 14 (seeFig. l) and comprises a body 37, bearing on the guy. 38 indicates asheave adapted to run on the guy, and 39 a shell facilitating theconnection with the carriage of a block 40, over which a loading-line 41is rove. Said. line is provided in one 'end with tongs 42 or other meansfor attaching the logs, and aft-er passing' the block 40 theloading-line is reve over a block 43, and thence passes down to a drum44 of the hoisting-engine. By this gear the logs may be hoisted onto therailway-car or other vehicle intended for the transportation of thetimber.

The novel form of our loading-carriage is illustrated in Figs. 8, 9, andlO. The body 37 is formed with a groove 37 on its under side, which fitsit snugly to the guy 20. U-bolts 37b are engaged with the body and passaround the under side of the guy to clamp the body firmly to the guy. Atits upper end the body is formed with a fork 37C, carrying a pin 37. Onthis pin the sheave 38 is mounted. The shell 39 comprises twocheek-pieces 39, hung at their upper ends on the pin 37b and connectedat their lower end with a pin 39h. vWith this pin the block 40 isengaged in any suitable manner. The sheave 38 bears the weight of thelog` during the loading operation and also permits the carriage to berun freely over the guy during the operation of adjusting the carriage,for which purpose the U-bolts 37h are slacked. After the carriage isproperly adjusted it is clamped fast by the U-bolts.

Having thus described the preferred form of our invention, what we claimas new, and desire to secure by Letters Patent, is#
